I have a Potterton Housewarmer 45 which about a year ago started to make a roaring sound when the boiler fired up. I turned the boiler off and had it serviced and cleaned and it has behaved perfectly since, until recently the fault has restarted.
The roaring sound is caused by the burner igniting in the lower chamber of the gas burner. The stainless steel gauze filter has been cleaned .This usually occurs at the initial start up each day (when the flue is cold?) The boiler has been cleaned and a new gas valve has been fitted but the problem seems to be getting worse. A corgi engineer has been and reset the burner pressure but the problem is still occurring. Can any experienced Corgi engineer help?
